Cryptographic algorithms executing on computing devices may use one or more keys to encode and decode transmitted and received messages. Keys may be exchanged over a networked environment so that authorized computing devices may cipher and decipher such transmitted and received messages. In some types of networks in which a geographical span and/or number of associated computing devices may change or be logistically challenging to manage for example, conventional methods of distributing a key from a central source may be inadequate. For instance, coordinating the sharing, exchanging, or distribution of cryptographic keys for use may pose operational challenges. As an example, multiple authorities operating at different administrative levels may distribute different keys for use with cryptographic algorithms. A main datacenter may distribute cryptographic keys different from the cryptographic keys distributed by a base station. The cryptographic keys from the main datacenter may encode and decode differently from cryptographic keys distributed by the base station. In this scenario, mobile computing devices may move from within range of one authority to a range of another authority. As the communication range extending from a given authority may be geographically restricted, there may be a limited time window in which to distribute new cryptographic keys to all the computing devices connected to the various networks. New cryptographic keys may be frequently generated and distributed, and therefore a coordination of mobile computing devices may be logistically difficult. Consequently, less than a subset of mobile computing devices may receive updated cryptographic keys for use in cryptographic algorithms, resulting in some mobile computing devices of the network not being able to encode and decode messages properly.
